Figure 1

Distribution of fragment enrichment with anti-Hsf immunopurified chromatin on the genomic tiling array. The y-axis plots the asinh transformation (approximately equivalent to the log₂ scale) of the ratio of anti-Hsf versus preimmune sera. The x-axis represents each of the 3,444 PCR products, the Adh region, Hsp gene and segmentation gene (Seg) sequences are indicated below the x-axis. Strong enrichment of fragments from the Hsp genes is indicated by their high ratio. The signals from l(2)35Bg and PRL-1 in the Adh region are indicated.
